To all whom it may concern.-

Be it known that I, CHARLES W. WRIGHT,

- a citizen of the United States, residing at strips thereof.

The object of my invention is to provide a parting-strip which will hold the sash tightly and prevent rattling and which will prevent ing-strip with the sash.

the lower portion of Fig. III.

the entrance of air or dust and also allow of the easy removal of the window-sash without the necessity of removing the parting-strip.

My invention consists in providing a parting-strip which is so attached within the pulley-piece of the frame as to be held outwardly against the sash by means of springpressure.

My invention also consists in providing a parting-strip which engages the sash both at the sides thereof and at the edges.

My invention further consists in features of construction which will be hereinafter fully set forth and claimed.

In the drawings, Figure I is a view of a portion of one side of a Window-frame and segmental portions of both sashes, illustrating the position and arrangement of the partingstrip when the same is in position. Fig. II is a cross-sectional view taken through one side of the frame and sash, also including the parting-strip and illustrating one manner of securing the same within the pulley-piece, also illustrating the engagement of the part- Fig. III illustrates a modified form of parting-strip when the same is formed partly of wood and partly of metal. This view is partly in section. Fig. IV is a cross-sectional view taken through Fig. V is a detached view, partly in section and enlarged, of a parting-strip, a cross-section of which is illustrated in Figs. I and II. y

In the drawings, A represents a windowframe pulley-piece which forms part of the frame. Located at each side of the pulleypiece A are the inner and outer slats or guidebars a b, respectively. The pulley-piece A is grooved vertically, as at A, to a depth sufficient to receive a of this groove and its width depending upon the depth of the parting-strip."

B represents the parting-strip, which is located in the groove A in such a manner that the groove sustains it from lateral movement, but will allow of the parting-strip to be depressed within the. groove. strip B may be made of any suitable materialas, for instance, as illustrated in Figs. I and II, it is formed of metal, and, as illustrated in Figs. IV and V, it is formed partly of metal and partly of wood. In any event the parting-strip B is provided at each side thereof and outside of the pulley-piece A with side parting-strip, the depth I The partingflanges f f, which engage both sashes, as-

illustrated in Fig. I and Fig. II, at the edges of the sash-rails C C and as at c c. There flanges ff are located a short distance from the projecting edges of the parting-strip, so that the said parting-strip will also engage the stiles of the sash at their opposite faces, as in the ordinary manner.

In order to provide for more secure engagement between the parting-strip and the Stiles of a window-sash, I prefer to form the outer edges of the flanges f f with slightlyoutturned portions f f, which fit into grooves g 9, formed in the edges of the stiles O C. These outturned portions f f of the partingstrip project at an obtuse angle to the flanges f f, that they may have a tendency to draw the stiles of the sash toward the sides of the parting-strip.

In order to provide for kee ing the parting-strip in engagement with t e stiles of the sash, I provide a spring 8, located to the rear of the parting-strip and between it and the bottom of the groove A and leave sufficient distance between the parting-strip and the bottom ofthe groove to allow the partingstrip to be depressed within the groove A. Also suflicient space is left between the rear of the flanges ff and the face of the pulleypiece to allow of the depression of the parting-strip. To prevent t e parting-strip from being forced outward beyond the groove, I prefer to employ screws 8 or other retaining means which in the case illustrated are surrounded by the springs S. Two of these screws 3 I consider suflicient for the purpose, one being located at the upper end and the other at the lower end, leaving a space between them suflicient for the passage of one sash. Thus when it is desired to remove the sash all that is necessary is to depress the parting-strip into the groove A and by push- I parting from my inventlon.

mg on the sash in the opposite direction, WlllC'll W111 111 turn depress the opposite partlug-strip, the sash may be easi y removed without removing the parting-strips or either of them. This facilitates the cleaning of the windows at the outside and at the same time provides a parting-strip which securely holds the sash in position and prevents rattling and the entrance of air or dust.

As illustrated in Figs. IV and V of the drawings, this partin -strip may be made of wood and be provided with a cap of metal in turn provided with the flanges ff. Other materials may, however, be employed for th partin -strip.

In illustrating and setting forth this invention I have mentioned and shown certain details of construction and arrangement of parts which I consider best adapted to obtain the objects of my invention, such as illustrating a spiral spring and a screw as a means of fastening; but I do not wish to be limited to these means, as under certain-conditions a flat spring may be employed of such curvature or contour as to produce the same results. Also the exact contour of the flanges ff and the parting-strip as a whole might be departed from in ccr'taiimlctails without do- What I claim is- 1. The combination with a window parting-stri comprising a channeled member adapter to engage the sides of the stiles of the sash, of transverse flanges carried by said channeled member and adapted to engage the ends of the stiles of the sash and springs for maintaining said parting-strip in engagement with said sash.

2. The combination with a window having 3 grooved pulley-piece, of a channeled winow sides of the stiles of the sash, flanges carried by said channeled parting-strip having outturned ends adapted to engage grooves formed in the ends of the stiles 0f the sash and springs located in said channeled member and tending to force the same into engagement with the sash.
